Radiation Emissions of Popular Smartphones

Smartphones have become an integral part of our everyday lives. From work and school to daily tasks, these handheld devices have brought everything into the palm of our hands.

Most people spend 5-6 hours on their phones each day. And, given that our phones emit a tiny amount of radiation, we’re exposing ourselves to radiation for hours each day.

But different phones emit different amounts of radiation.

With the help of data collected by the German Federal Office of Radiation Protection, we visualize the radiation emissions of some popular smartphones in the market today.

Radiation and SAR Values of Smartphones

Smartphones and other mobile devices emit tiny amounts of radiofrequency (RF) radiation. Humans can absorb this radiation when the smartphone is being used or is lying dormant anywhere near their bodies.

The parameter used to measure phone radiation emissions is the Specific Absorption Rate (SAR). It is the unit of measurement that represents the quantity of electromagnetic energy absorbed by the body when using a mobile device.

The Council of the European Union has set radiation standards for cell phones at 2 watts per kilogram, measured over the 10 grams of tissue that is absorbing the most signal.

SAR values are calculated at the ear (speaking on the phone) and at the body (kept in your pocket). For the purposes of this article, we’ve used the former calculations.

Smartphones With the Highest Levels of Radiation Emissions

The Motorola Edge has the highest radiation emission with a SAR value of 1.79 watts of radiation per kilogram. That’s significantly higher than most other smartphone models in the market today and close to the limits set by the EU for cellphones.

Coming in second is the Axon 11 5G by ZTE with 1.59, followed by the OnePlus 6T at a close third with 1.55 W/kg. The Sony Experia AX2 Plus with 1.41 and the Google Pixel 3 XL and 3A XL at 1.39 round out the top five.

Here is a look at the 10 smartphones that emit the highest level of radiation:

Now that we have detailed the worst offenders let’s look at the smartphones with the lowest levels of radiation emissions.

Smartphones With the Lowest Levels of Radiation Emissions

The smartphone with the lowest SAR value is the ZTE Blade V10, with 0.13 watts of radiation per kilogram.

Mobile devices by Samsung carry some of the least radiation risks. The company has four phones considered to be the best in the category. The Galaxy Note 10+ is the best model in their line-up, emitting a meager 0.19 watts per kilogram.

Here is a look at the 10 smartphones that emit the lowest levels of radiation:

There is currently no significant research proving the harmful effects of phone radiation.

Despite this, people who are in contact with their devices for extended periods can at least quantify their radiation exposure and make choices about which brands serve their needs.

Charted: The Jobs Most Impacted by AI

We visualized the results of an analysis by the World Economic Forum, which uncovered the jobs most impacted by AI.

Charted: The Jobs Most Impacted by AI

Large language models (LLMs) and other generative AI tools haven’t been around for very long, but they’re expected to have far-reaching impacts on the way people do their jobs. With this in mind, researchers have already begun studying the potential impacts of this transformative technology.

In this graphic, we’ve visualized the results of a World Economic Forum report, which estimated how different job departments will be exposed to AI disruption.

Data and Methodology

To identify the job departments most impacted by AI, researchers assessed over 19,000 occupational tasks (e.g. reading documents) to determine if they relied on language. If a task was deemed language-based, it was then determined how much human involvement was needed to complete that task.

With this analysis, researchers were then able to estimate how AI would impact different occupational groups.

DepartmentLarge impact (%)Small impact (%)No impact (%)

Finance70219
Customer Sales671617
Operations651817
HR57412
Marketing56413
Legal46504
Supply Chain431839

In our graphic, large impact refers to tasks that will be fully automated or significantly altered by AI technologies. Small impact refers to tasks that have a lesser potential for disruption.

Where AI will make the biggest impact

Jobs in information technology (IT) and finance have the highest share of tasks expected to be largely impacted by AI.

Within IT, tasks that are expected to be automated include software quality assurance and customer support. On the finance side, researchers believe that AI could be significantly useful for bookkeeping, accounting, and auditing.
